T1566.001 Spearphishing Attachment
T1059.007 JavaScript
This PDF file contains numerous links to external websites, a common tactic for phishing or malware distribution. One prominent URL, 'https://yafferge.ru/strik?utm_term=curso+de+marketing+digital+online+gr%25C3%25A1tis+com+certificado', is flagged as a malicious redirector, suggesting it leads to a malicious payload or phishing page. The document body, though partially corrupted, indicates a lure related to a free digital marketing course, aligning with phishing pretexts. The presence of many PDF links and a malicious redirector strongly suggests a phishing or malware distribution campaign.

PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINKPDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
-
Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
-
Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTALThe same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
-
Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL https://yafferge.ru/strik?utm_term=curso+de+marketing+digital+online+gr%25C3%25A1tis+com+certificado In PDF document text
